| 00:30 | < RichyB> | IIRC negative bases work. Three in base -2 is 101. |
| 00:30 | < RichyB> | er |

| 00:31 | | You're now known as TheWatcher[zZzZ] |
| 00:39 | <~Vornicus> | yep. |
| 00:39 | <~Vornicus> | you can also get irrational bases and complex ones; knuth actually describes base 2i somewhere |
| 00:43 | <@Reiv> | ... what. |
| 00:44 | <~Vornicus> | Which actually isn't too terribly weird |
| 00:45 | <~Vornicus> | well, okay, it is |
| 00:46 | <~Vornicus> | You take base -4: from -10 to +10 it's 32, 33, 20, 21, 22, 23, 10, 11, 12, 13, 0, 1, 2, 3, 130, 131, 132, 133, 120, 121 |
| 00:47 | <~Vornicus> | and then interleave that with the digits for 2*Im(z) |
| 00:47 | <@Reiv> | ... Im(z) |
| 00:47 | <~Vornicus> | imaginary part of the complex number z |
| 00:47 | <@Reiv> | I... see |
| 00:47 | <~Vornicus> | Re(2i + 3) is 3; Im(2i + 3) is 2 |
| 00:48 | <@Reiv> | The real vs Im component of the number, right |

| 15:59 | <&Derakon> | For some reason this bit of code makes me happy. Given xVals and yVals, the X and Y pixels of a bead in an image, and x and y, their averages: |
| 15:59 | <&Derakon> | xDists = [(x - xi) ** 2 for xi in xVals] |
| 15:59 | <&Derakon> | yDists = [(y - yi) ** 2 for yi in yVals] |

| 16:12 | < RichyB> | Derakon: yeah, that's neat. |
| 16:13 | < RichyB> | It's lovely when comprehensions allow the code to look just like the equation in the geometry textbook. |
| 16:14 | <&Derakon> | I also appreciate that I didn't have to do a single square root. |

| 17:09 | <&Derakon> | Yeah, it's not so much about shoving as much functionality onto one line as you can. |

| 23:40 | <&Derakon> | "The moral is obvious. You can't trust code that you did not totally create yourself. (Especially code from companies that employ people like me.)" -- Ken Thompson |
| 23:40 | | * Derakon is just rereading his ACM presentation on the trojan horse he inserted into UNIX. |
| 23:40 | <&Derakon> | ( http://cm.bell-labs.com/who/ken/trust.html for those who have not read it before) |
| 23:41 | <&Derakon> | Short version: modify the compiler to recognize when it is compiling the UNIX login command, and insert a special password option so Ken could login to any system compiled with that compiler. |
| 23:42 | <&Derakon> | Then modify the compiler to recognize when it was compiling itself, and insert the code that does the above modification as well as the code that does this modification. |
| 23:42 | <&Derakon> | Then revert the changes to the compiler's source code and recompile it. |
| 23:43 | <&Derakon> | Ta-da: any time that compiler compiles itself or the login command, it will produce a subverted binary. |
| 23:43 | <&Derakon> | With no evidence in the source code. |
| 23:47 | <~Vornicus> | That is one of the greatest essays on programming ever made. |
